ALBIN PAUL METHOD OF AND APPARATUS FOR ENAMELING.

SPECIFICATION forming part of Letters Patent No. 605,903, dated June 21,1898.

Application filed October 16,1897. Serial No. 655,478. (to model.)

divided by a horizontal perforated partition or floor b, forming thebottom of a compartment C, and which supports the article tobe treated.

Arranged in the compartment 0 is a horizontal shutter D, which is abovethe article to be treated, and at each side of the same are shutters DThe shutters D are connected by suitable ropes or chains cl, passingover a suitable pulley df and joined to a single rope or chain (1 bywhich means the side shutters maybe raised or lowered. The horizontalshutter D is provided with a rod 01 by means of which the same may beraised or lowered at Will.

In the embodiment of myinvention now illustrated the receptacle for theingredients of the enamel is between the partition I) and the bottom ofthe shell, which bottom is preferably curved, as shown.

Mounted in the receptacle B is a shaft 1), upon which are arranged aseries of wings 2 of sheet metal or other suitable material. The outerend of the shaft 19 is provided with a band-wheel 17 through whichmotion is communicated to the shaft and the wings carried by it.

In the operation of my invention the quantity of the ingredients of theenamel to be used To all whom it may concern.-

Beit known that l, ALBIN PAUL OTTO, a citizen of the United States,residing at Trenton, in the county of Mercer and State of New Jersey,have invented certain new and useful Improvements in Methods of andApparatus for Enameling; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to enameling, and it relates particularly to thatbranch of this art which contemplates the coating of articleswith'enamel the ingredients of which are apfinely-divided condition.

The object of the invention is to produce a mode of procedure and meanswhereby a coating of enamel, uniform in thickness over the entiresurface coated, may be placed upon articles in a rapid manner, producinga superior quality of enameling with saving of time over theusually-practiced methods of enameling.

The invention consists, essentially, in the art of enameling, whichconsists in the method of applying finely-divided enamel by heating thearticle to be enameled, confining the article, projecting throughout thespace surrounding the same the ingredients of enamel in a finely-dividedstate, and then in more closely confining the article and allowing theenamel ingredients to settle on the article.

The invention consists, further, in various novel details ofconstruction, whereby the objects of the invention are attained and theeffectiveness of the device insured.

The apparatus for carrying out my invention is illustrated in theaccompanying drawpart of the apparatus. The article to be treated isheated, preferably, to a cherry red and placed in the apartment 0, theshutter D being raised and the shutters D being lowered in order to givethe greatest area to the apartment 0. After the article is introducedthe apartment 0 is closed revolved rapidly, resulting in projecting intothe apartment 0 the ingredients of the enamel. The result of this mannerof introducing the enamel is to distribute the same uniformly throughoutthe apartment C, and thus an ings, in whicheven coating will be placedupon the article Figure 1 is a perspective view of the appato beenamelec WVhen a sufiicient quantity ratus. Fig. 2 is a transversesectional View, of enamel has been deposited upon the'artiand Fig. 3 isa front elevation. cle treated, the shutter D is lowered and theshutters D raised, thus materially decreasing the area of the apartmentand resulting in shutting off all enamel except that inclosed within theshutters.

While I have particularly described the shutter provided with wings asthe means for In the drawings, A represents the shell or outsidecovering of the apparatus, which may be of any suitable material notinjuriously affected by heat, the interior of which forms an inclosingchamber for receiving the article to be enameled. The interior of theshell is is first placed in the receptacle B in the lower and the shaftB is projecting the enamel upon the article to be course limit myself inthis coated, I do not of respect, as any other suitable mechanical meansfor the purpose may be employed.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In the art of enameling the method of applying finely-divided enamelby heating the article to be enameled, confining the article, projectingthroughout the space surrounding confining the article, thereby limitingthe quantity of enamel applied, and allowing the enamel ingredients tosettle on the article, substantiallyas described.

2. An apparatus for enameling comprising a closed apartment, areceptacle adjacent to the apartment for receiving the ingredients ofthe enamel, means for projecting the ingredients throughout theapartment, and

movable shutters for decreasing the size of the apartment, substantiallyas described.

An apparatus for enameling comprisin perfopartition and throughout theapartment, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

ALBIN PAUL OTTO.
